REGISTER.

SPECIFICATION forming part of Letters Patent No. 687,007, dated November19, 1901.

Application filed February 18, 1901. Serial No. 47,828. (No model.)

T at whom it may concern:

Be it known that 1, WILLIAM A. Foss, a. resident of Cleveland, in thecounty of Cuyahoga and State of Ohio, have invented certain new anduseful Improvements in Telephone-Call Registers; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it topertains to make and use the same.

My invention relates to improvements in telephone-call-registeringmachines, and pertains more especially to a machine of the characterindicated that is provided with a device or mechanism for signaling tothe central station or telephone-exchange upon the operation of theregister.

The object of this invention is to provide a construction that is simpleand reliable in its operation and not liable to get out of order.

With this object in View the invention consists in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claim.

In the accompanying drawings, Figure I is a front side elevation of atelephone-call register embodying my invention, and portions of theinclosing case of the machine are broken away and in section to moreclearly 0 show the construction. Fig. II is a front side elevationcorresponding with Fig. I, except that in Fig. 11 the front wall of thecase is entirely removed and the operating parts of the signal-producingmechanism are shown 5 in a diiferent position. Fig. IIIis a left-handside elevation in section on line III III, Fig. I. Fig. IV is a verticalsection on line IV IV, Fig. I, showing the operating-shaft of theregister and the shaft-turning sleeve.

Referring to the drawings, a designates the inclosing case of themachine. A register I), which may be of any approved construction, isarranged within and suitably secured to the case a, and c designates theoperatingshaft of the register. In the machine illus- Within the upperportion of the case, above the register I), is provided a gong d, whichis secured to the case in any approved manner, and e represents anupright gong-sounding hammer which is located at the right-hand side ofthe gong and normally arranged in close proximity but out of contactwith the gong and is rigidly secured at its lower end to the upper armor portion of an upright lever f, which is fulcrumed, as at f, at ornear its central portion and horizontally forwardly and rearwardly ofthe machine to a lug or arm a, projecting forwardly from and formed uponor rigid with the rear wall of the case a at the right-hand side of andbelow the central portion of the gong. The lower or depending arm orportion of the leverfnormally engages the cam-forining surface g of acain'wheel g, which has a hub g rigidly secured to the shaft 0 by meansof a setscrew it, and consequently the cam-wheel. is operativelyconnected with the shaft. The hammer bearing lever is arrangedtherefore, above the shaft 0, with its axis arranged at right angles tothe axial line of the shaft, and the cam-wheel is arranged below theaxis of the lever between the register and the forward or outer portionof an arm or bracket a provided within the case a, and affording bearingfor the shaft and formed upon or rigid with and projecting forwardlyfrom the rear wall of the said case. The camforming surface g of thecam-wheel is arranged concentrically of the shaft and faces theregister. The said cam-forming surface extends spirally around the shaftin the direction of the register, and in the normal position of theparts the lower or depending arm or portion of the lever f engages thatend of the spirally-arranged camforming surface which is farthest fromthe register and extends in front of a shoulder 9 which is formed uponthe cam-wheel between the ends of the spirally-arranged cam-formingsurface and faces in a direction opposite to the direction in which theshaft is turned during the operation of the register. The register andthe cam-wheel are simultaneously operated, and the shaft is turned inthe direction indicated by the arrow in operating the said wheel andregister. A suitably-applied spiral spring 75 is arranged forward of andextends transversely of the lower portion of the gong and acts to retainthe lever f, and consequently the gong-sounding hammer, in their normalposition. The spring is attached at one end, as at 7t, to the upper armor portion of the leverfand has its opposite end attached to the case a.

Bythe construction hereinbefore described it will be observed that uponturning the shaft in the direction indicated by the arrow as required tooperate the register, as already indicated, the cam-wheel g is turned inthe direction required to tilt or oscillate the leverfin the directionrequired to move the gong-sounding hammer farther from the gong againstthe action of the spring 70, and

the said hammer is arranged farthest from the gong when that end of thespirally-arranged cam-forming surface g of the camwheel that is nearestto the register engages the lower or depending arm or portion of thelever, as shown in Fig. 11, just preparatory to a complete rotation ofthe shaft 0, and obviously the said 1ast-mentioned arm or portion of thelever upon a farther rotation of the shaft in the same direction will bereleased from the last-mentioned end of the aforesaid cam-formingsurface subject to the action of the spring when the spring will actuatethe said lever to effect the striking of the gong by the hammer borne bythe lever. The cam-forming surface g forms a stop to limit the tiltingor oscillation of the lever during the gong-operating actuation of thelever, and the aforesaid shoulder g of the cam-wheel and the dependingarm or lower portion of the leverf form a stop for preventing orlimiting a return movement of the shaft upon the completion of theoperation of the lever by the cam-wheel upon the operation of theregister.

The means for operating the shaft 0 comprises, preferably, two arms 0and c, with which the said shaft is provided at opposite sides,respectively, of the shaft between the arm or bracket 0, and the innerside of the right-hand side wall of the case a. A sleeve Z is introducedthrough a corresponding hole (1 formed in the said last-mentioned wallof the case in line with the shaft. The sleeve Z is large enough,diametrically, to render it capable of being slid onto the arm -bearingportion of the shaft and has two diametrically oppositely located slotsZ and Z, arranged to register with the different arms 0 and 0', respectively, of the shaft upon the application of the sleeve, and theengagement of the said arms of the shaft with the slots in the sleeveforms such an operative connection between the sleeve and the shaft aswill render the shaft capable of being turned by the sleeve. Theshaft-turning sleeve is long enough to extend when applied outside ofthe case a a suitable distance and has its outer end provided with acrank or handle Z for turning the same. The arms 0 of the shaft areformed, preferably, by a pin extending centrally through andtransversely of the shaft and projecting beyond opposite sides of theshaft the distance required to form the said arms, as shown in Fig. IV.

My improved machine is attached or placed in close proximity to thetransmitter-case or transmitter-bearing board of a telephone in anyapproved manner; but as the application of telephone-call registers iswell understood by those skilled in the art illustration or furtherdescription of the application of my improved machine is not considerednecessary in this specification.

hat I claim is- In a telephone-call register, the combination, with aregister, a shaft instrumental in the operation of the register, a gongor soundyielding body, a lever provided with a hammer for striking thesound-yielding body, and a suitably-applied spring acting to retain thehammer in close proximity or next to the gong or sound-yielding body, ofa cam-wheel operatively connected with the shaft and having acam-forming surface extending spirally around and arrangedconcentrically of the axis of the wheel and engaging the aforesaidlever, and means for turning the shaft, and the arrangement of partsbeing such that the cam-wheel shall, during the rotation of theaforesaid shaft in the direction required to operate the register,actuate the aforesaid lever against the action of the aforesaid spring,substantially as and for the purpose set forth.

Signed by me at Cleveland, Ohio, this 15th day of February, 1901.

WILLIAM A. FOSS.
